Port bond modes for E5700SG controller ports
When configuring network links for the E5700SG controller ports, you can use port bonding for
the 10/25-GbE ports that connect to the Grid Network and optional Client Network, and the 1-GbE
management ports that connect to the optional Admin Network. Port bonding helps protect your
data by providing redundant paths between StorageGRID networks and the appliance.

You can configure network links for the ports used to connect the appliance to the Grid Network,
the Client Network, and the Admin Network. You can set the link speed as well as the port and
network bond modes.
Network bond modes for the 10/25-GbE ports
The 10/25-GbE networking ports on the E5700SG controller support Fixed port bond mode or
Aggregate port bond mode for the Grid Network and Client Network connections.
Fixed port bond mode
Fixed mode is the default configuration for the 10/25-GbE networking ports.
Callout
Which ports are bonded
C
Ports 1 and 3 are bonded together for the Client Network, if this network is used.
G
Ports 2 and 4 are bonded together for the Grid Network.
When using Fixed port bond mode, you can use one of two network bond modes: Active-Backup
or Link Aggregation Control Protocol (LACP).
•
In Active-Backup mode (default), only one port is active at a time. If the active port fails, its
backup port automatically provides a failover connection. Port 4 provides a backup path for
port 2 (Grid Network), and port 3 provides a backup path for port 1 (Client Network).
•
In LACP mode, each pair of ports forms a logical channel between the controller and the
network, allowing for higher throughput. If one port fails, the other port continues to provide
the channel. Throughput is reduced, but connectivity is not impacted.
Note: If you do not need redundant connections, you can use only one port for each network.
However, be aware that an alarm will be raised in the Grid Manager after StorageGRID is
installed, indicating that a cable is unplugged. You can safely acknowledge this alarm to clear it.
Aggregate port bond mode
Aggregate port bond mode significantly increases the throughout for each StorageGRID network
and provides additional failover paths.
